Endpoint Structure Reference

This file serves as a reference for the Endpoint Structure pattern used in EVYOS backend services.
When addressed, this file helps to understand the pattern structure and implementation.

The pattern consists of three main components:
1. Events Component
2. Endpoints Component
3. Validations Component

Below is a simplified implementation example that demonstrates the structure.
